NEW YORK (JTA) -- U.S. Secretary of Defense Leon Panetta said it would take Iran approximately one year to build a nuclear bomb.

"The consensus is that if they decided to do it, it would probably take them about a year to be able to produce a bomb and then possibly another one to two years in order to put it on a deliverable vehicle of some sort in order to deliver that weapon,” Panetta said in an interview that aired Sunday on the CBS show “60 Minutes.”

Panetta said the U.S. would take “whatever steps are necessary” to prevent Iran from developing a nuclear weapon, calling it a “red line” for both Israelis and the United States. Asked about the possibility of U.S. military action, Panetta responded that “there are no options that are off the table.”
